M2.7.5 For the adult

Sorting diagrams

A number fits neither circle. Where do I put it?

What this chapter teaches

A sorting diagram sorts by rules. A Venn diagram has two circles: a number that fits both rules goes in the overlap, and one that fits neither goes outside both circles but inside the box. A 2 by 2 table sorts the same way.

Three questions to ask

There is no one right wording. Listen for the idea.

  1. Where would you put a number that fits neither rule, and why not leave it out?
  2. Which numbers up to 12 are both even and over 8?
  3. How is a 2 by 2 table like a Venn diagram, and how is it different?

After the chapter, the learner can

  • Sort numbers in a Venn diagram with two circles
  • Sort numbers into a 2 by 2 table using two rules

What they copy into their notebook

A Venn diagram sorts by two rules. A number that fits both goes in the overlap. A number that fits neither goes outside both circles, inside the box. A 2 by 2 table sorts the same way.
